“…Raworth 2004). This prediction is supported by Raworth et al (2008); 7 out of 938 trap plants placed in two BlScV-positive blueberry fields for 2-wk periods during 2001-2003 became infected in June and July while one became infected in May, and no other infections were detected. This result also concurs with Bristow et al (2000).…”

Seasonal variation in relativeBlueberry scorch virus(BlScV) concentration was determined for three infected highbush blueberry,Vaccinium corymbosum, cultivars in a commercial field in southwestern British Columbia, Canada. Relative virus concentration per g of infected blueberry flower clusters and leaf terminal tissue varied during the season with significant cultivar-by-time interactions. Flower clusters had the highest BlScV concentration per g of tissue and could be collected in early May for disease surveys. Timing of leaf sample collection for BlScV surveys, transmission studies and virus purification should be based on studies of temporal variation in BlScV concentration for the principal cultivars in a production area.

“…Raworth, 2004. Bristow et al (2000) suggested that E. fi mbriata is an inefficient vector of BIScV, which was confinned by Raworth et al (2008) where only 2 and 6 out of 119 and 123 trap plants, respectively, with this aphid present, in two separate fields with BISeV, became infected. Important vectors in other areas have not been determined.…”

“…Identification of diseased bushes should he based on laboratory tests rather than symptoms since symptom expression varies by blueberry cultivar and virus strain. In addition, the testing needs to be continued for 3-4 years since the virus can be unevenly distributed in a hush and the virus titers call very slowly over several years (Raworth et al, 2008).…”

It should be expected that as blueberry cultivation continues to expand into new areas, the plants will become exposed to viruses that have not previously been observed in blueberry. Since the last symposium in 2004, Blueberry scorch virus continues to be a major concern in the USA Pacific Northwest and it has also been detected in New England as well as the Netherlands and Italy in Europe. In the past, blueberry mosaic symptoms appeared to spread very slowly or not at all, while in recent years, the disease has been spreading within fields and appearing in new fields. Blueberry mosaic symptoms have been observed in many production areas. A high molecular weight double-stranded RNA (dsRNA) has been detected in plants with mosaic symptoms indicating the presence of a virus, but the virus has yet to be characterized. Blueberry red ringspot virus has been detected in the southeastern USA. A virus has been detected in plants exhibiting Blueberry fruit drop symptoms in the Pacific Northwest. In cranberry, funky flower symptoms have been observed in the northeastern USA for the past 10 years. Recently, Cucumber mosaic virus has been detected in plants exhibiting funky flower symptoms. Efforts to demonstrate a causal relationship between Cucumber mosaic virus and disease symptoms are underway. Tobacco streak virus was first reported from cranberry plants imported into Scotland and has since been detected in New Jersey. A breakthrough in detection of viruses in Vacciniu#n species has come from the development of a dsRNA extraction method that works reliably with blueberry and cranberry. Cloning and sequencing of purified dsRNA has been the most successful means for the characterization of viruses of woody plants that can not be transmitted to herbaceous hosts.

Molecular characterization of two distinct strains of blueberry scorch virus (BlScV) in northern Italy

During blueberry scorch virus (BlScV) surveys of highbush blueberries in Italy between 2005 and 2010, we initially discovered infected orchards only in Piedmont. Since 2009, however, three infected orchards have also been found in Trentino, where a new host species, Vaccinium ashei, was found to be infected by BlScV. Molecular characterization of isolates during the study period suggests that two very distinct epidemics are now present in Italy: the Piedmont isolates belong to a new BlScV strain, whereas the Trentino isolates are almost identical to the Washington State strain.
